I've recently noticed that I cannot seem to create mfs partitions in
excess of 247MB. This is on an SS20 with 512mb ram and dual hypersparcs
running GENERIC.

temporal: {1} mount_mfs -s 512m swap /usr/obj
temporal: {2} df -h

mfs:16885     247M     1.0K      235M     0%    /usr/obj

Top reports 430mb ram and 1010mb swap free.

I've scanned Google with no success. Is such behavior normal for this
architecture? On i386 I can mount mfs partitions well in excess of this
amount. Interestingly, I can mount however many 247MB partitions I
please.

Thanks,
